A unique feature of the
Revelation of Bahá'u'lláh is the authenticity of its revealed
Word. Unlike the teachings of Christ, for example, which were written down decades after
they were uttered, the words of Bahá'u'lláh were recorded and authenticated at the time
they were revealed.

The process of
revelation--as Bahá'ís term the act of bringing forth the Word of God--is described in
several historical documents. One observer recorded the following:

"Mirza Aqa Jan (Bahá'u'lláh's personal secretary) had
a large ink-pot the size of a small bowl. He also had available about ten to twelve pens
and large sheets of paper in stacks. In those days all letters which arrived for
Bahá'u'lláh were received by Mirza Aqa Jan. He would bring these into the presence of
Bahá'u'lláh and, having obtained permission, would read them. Afterwards [Bahá'u'lláh]
would direct him to take up his pen and record the Tablet which was revealed in reply...

"Such was the speed with which he used to write the
revealed Word that the ink of the first word was scarcely yet dry when the whole page was
finished. It seemed as if someone had dipped a lock of hair in the ink and applied it over
the whole page."

After each period of Revelation, the original manuscript
would be re-transcribed, with Bahá'u'lláh Himself overseeing and approving the final
version.

"The Word of God is the master key for the whole world, inasmuch
as through its potency the doors of the hearts of men, which in reality are the doors of
heaven, are unlocked."--Bahá'u'lláh
